A therapeutic agent for osteoporosis brought about by a decrease in estrogen comprises an extract from inflammatory rabbit skin inoculated with vaccinia virus as an effective component. In ovariectomized rats, a model animal for osteoporosis brought about by a decrease in estrogen, the extract from inflammatory rabbit skin inoculated with vaccinia virus has an excellent action for maintaining bone volume and bone strength. The therapeutic agent containing the extract as an active component is very useful for treatment and prevention of osteoporosis brought about by a decrease in estrogen which is frequently caused by menopause or ovariectomy in women. The extract from inflammatory rabbit skin inoculated with vaccinia virus has a high safety profile even when administered for a long term.

Peptide fragments and their pharmaceutically acceptable salts, and therapeutic agents containing one or more of them as an effective component possess excellent therapeutic activity for improving cerebral function and protecting cerebral neurons and are useful as pharmaceutical agents. The peptide fragments of the present invention are amino acid residue peptide fragments of acid fibroblast growth factor (aFGF) of mammalian animals or humans which do not contain cysteine at the 16-position. The compounds include a 1-29 amino acid residue peptide fragment of acid fibroblast growth factor in which cysteine, an amino acid at the 16-position, is substituted with another amino acid, such as alanine, serine, or glutamic acid, and pharmaceutically acceptable salts thereof. The compounds also include a 1-15 amino acid residue fragment of acid fibroblast growth factor of mammalian animals or humans and pharmaceutically acceptable salts thereof. The protein fragments may have an N-terminal group which is in amide form or free form. In a passive avoidance learning test and in a maze-learning test in water, the peptides of the present invention exhibit an excellent action of improving the learning and the remembering ability of senility-accelerated mice in which remembering and learning abilities were reduced. The peptide fragments also exhibit a protective effect against the death of cerebral neurons caused by ischemia. As such, the compounds of the present invention show excellent improvement of brain functions and protection of cerebral neurons. The compounds are useful as a pharmaceutical agent for dementia and other diseases caused by reduction of various brain functions.

The present invention provides silicate polymers which regulate the function of a living body by restoring and normalizing the lowered cell functions due to diseases. The silicate polymers are preferably water soluble. The molecular weight of the polymers is in the range of 4,800 to 2,000,000, preferably 20,000 to 1,000,000, and they have a degree of polymerization in the range of 75 to 33,000, preferably 490 to 16,500. The monomer unit is (SiO.sub.2). The polymers may be produced by dissolving a water-soluble silicate or a silicic acid containing material such as water glass in water to obtain an aqueous solution. The solution may be admixed with an acid to adjust the pH to 2-10, preferably 4-9.5. A saccharide or sugar alcohol or pharmaceutically acceptable salt may also be admixed with the solution. The aqueous solution is preferably dried to obtain a powder by heating at 150.degree. C. to 250.degree. C. or by lyophilization. The pharmaceutical composition may be used to treat or prevent various diseases, ailments or symptoms associated with allergies, inflammation, or pain.

The present invention provides a method for measuring the activity of tested substances utilizing a reconstituted plasma kallikrein-kinin system. A series of enzymatic reactions is started wherein an activation of a blood coagulation factor XII is an initiating reaction. The series of reactions is started in the presence of the tested substance in the reconstituted plasma kallikrein-kinin system. Then, the series of reactions is stopped and the physiologically active substance produced in the reaction series is quantitatively determined. In the activity measuring method of the present invention, the real activity (a promoting or inhibiting ability) of the tested substance against the production of the produced physiologically active substance can be easily, simply, quickly and precisely measured. In the reconstituted plasma kallikrein-kinin reaction system the contaminating other factors are substantially removed. Accordingly, the method of measuring the activity in accordance with the present invention is a very advantageous means for ascertaining action which is useful for adjusting the bioregulations in, for example, the plasma kallikrein-kinin system, the blood clotting system, the fibrinolysis system, etc. It may also be used for developing or screening drugs which are related to the systems.
